Owners report 'Critical Electrical Failure' messages and stalling, often linked to water pump coolant leaks damaging the vacuum system. These can leave you stranded and are costly to fix.
The main water pump can fail prematurely, allowing coolant to enter the vacuum system, and some owners report unintended acceleration when shifting. These are serious drivability and safety concerns.
Transmission error messages, such as 'Reverse gear not available,' are reported, which can limit gear selection and require dealer attention. This can affect everyday usability.
Stalling under normal driving conditions and recall-related coolant pump humidity issues are noted. Stalling can be dangerous in traffic and needs immediate diagnosis.
“The main water pump on my 2018 Porsche Panamera 4S failed prematurely. This is not a simple external coolant leak; the internal seal failed, allowing pressurized engine coolant to migrate into the vehicle's vacuum system. The coolant traveled through the vacu…”
“A message appeared on the dashboard indicating a "Critical Electrical Failure" and "Park Safely" when I turned the key to start the car. This car is a plug-in e-hybrid (my 3rd of this model) and I always assumed that in case of a major failure, I could either…”

Owners of 2026 models report engine failures with the 6.2L motor and diesel particulate filter soot accumulation on the 6.6L Duramax, leading to loss of power. These can require major repairs and leave you stranded.
Complaints include sudden shifting into neutral and transmission problems, sometimes with very low mileage. This can cause loss of control and unexpected stops.
Reports of severe braking loss and engine pinging with loss of motive power, brakes, and steering. These are critical safety failures that demand immediate attention.
Owners describe sudden loss of normal braking with a firm pedal but ineffective stopping. This is a major safety hazard and should be inspected before purchase.
“I purchased the 2026 Chevrolet Silverado with a 6.2L motor "new" from the dealer with 5700 miles on XXX. Roughly a month and 2500 miles later, my family and I were in the vehicle, 750 miles from home, returning from a vacation to [XXX] from the [XXX]/[XXX] ar…”
“My 2026 Chevrolet Silverado 3500 with the 6.6L Duramax diesel has experienced three separate P2463 Diesel Particulate Filter excessive soot accumulation events at approximately 4,300, 5,500, and 10,280 miles. Each event required a Chevrolet dealer to perform…”

Buyer analysis
Porsche Panamera or Chevrolet Silverado: which should you buy?
The Porsche Panamera has far fewer complaints per year (2.6 vs. 510.5), but both have significant issues. The Silverado's higher volume means more reported problems, while the Panamera's lower volume still includes serious failures. In practice, the Panamera may have fewer overall incidents, but each could be costly; the Silverado's widespread issues mean higher odds of encountering a problem.
Key differences
- Complaint volume: Panamera averages 2.6 per year; Silverado averages 510.5 per year, indicating far more reported issues for the Silverado.
- Crash-related complaints: Silverado has 117 crash-related complaints and 104 injuries; Panamera has 1 crash-related and 2 injuries, suggesting different safety risk profiles.
- Recalls: Silverado has 100 recalls vs. Panamera's 21, meaning the Silverado has more known issues requiring manufacturer fixes.
- Reported failures: Panamera owners report water pump leaks and transmission errors; Silverado owners report engine failures, brake loss, and sudden neutral shifts.
- Check for coolant leaks or water pump failure signs, such as low coolant or white smoke, as this can lead to vacuum system damage.
- Test the transmission for error messages or delayed engagement, especially when shifting between reverse and drive.
- Listen for engine pinging or knocking and check for loss of power, which may indicate engine failure or diesel particulate filter issues.
- Test the brakes for any loss of braking effectiveness, especially after driving a short distance, as sudden brake loss has been reported.
Before you buy
- Obtain a full vehicle history report and check for open recalls on the NHTSA website using the VIN.
- Have a certified mechanic inspect the vehicle, focusing on the engine, transmission, brakes, and electrical system.
- For the Panamera, specifically check the water pump and vacuum system for coolant contamination.
- For the Silverado, test drive at various speeds and braking conditions to detect transmission or brake issues.
- Ask the seller for maintenance records and confirm that all recall repairs have been completed.
